How does the FS call the correct call sign on add on aircraft.

You must download and install them using Edit Voicepack. It is very easy to use. Also, many PAI packages include callsings, but not all. Finaly, Flight Simmulator knows which to use by this entry inthe Aircraft.cfg file:

kb_reference=Boeing737-400_ref
atc_id=N700MS
atc_airline=Skywest <--------this one
atc_flight_number=1123
ui_manufacturer=Boeing
ui_type=737-700 - The 737 Experience

Edit voicepack will install thousands of callsigns!

"22. Flight Plan Parameters that Override Aircraft.cfg

Every FS aircraft comes with a file named aircraft.cfg that specifies numerous parameters for the aircraft and its various sub-models (paint schemes). Three parameters in that file can be overridden by AI flight plans:

atc_id=N700MS
This will be ignored for an AI aircraft. AI will always use the registration number supplied in the flight plan.

atc_flight_number=1123
This will also be ignored for an AI aircraft. AI will always use the flight numbers supplied in the flight plan.

atc_airline=Orbit
If this is specified in the aircraft.cfg file then the AI aircraft will normally use the airline name as part of its call sign along with the flight number specified in the flight plan, for example "Orbit 3401". AI flight plans cannot change the airline, but if the "F or R" flag is set to

And of course there is the EXPERIMENTAL that will be used by ATC if it does not recogonize the airline.
